- the top edge of the wall 172 is separated by an air gap 148 from the bottom side of the table top 2. While some of the structures described in the present disclosure are directed to limiting access of a user to internal compartments of the table saw defined by the space defined by the air gap 148, some of the other structures are directed to limiting access of the user to the space adjacent the motor 40.
- the guard system 180 is optionally a spring-loaded guard system with guard members that pivot about a pivot axis 181.
- the guard system 180 includes guard members such as a top guard plate 182 and side plates 184 shaped in the form of triangles which are integrally formed on opposite sides of the top guard plate 182 forming a unitary U-shaped structure providing added rigidity.
- the guard system 180 also includes a glide wire (or a rail member) 186A, a clip 186B, and an optional torsion spring 186C.
- the glide wire 186A is a U-shaped structure and directs the top guard plate 182 and the side plates 184 to slide according to the predefined path of the glide wire 186A.
- the glide wire 186A is connected to the motor 40 by a three-point connection arrangement.
- the clip 186B connects the base of the U-shaped glide wire 186A to the motor 40, while the ends of the U-Shaped glide-wire 186A are connected to the motor 40 at mounting holes 186D positioned on opposite sides of the motor 40 (only one mounting hole 186D is depicted in FIG. 3 ).
- the optional torsion spring 186C urges the top guard plate 182 and side plates 184 downward toward the motor 40, while the glide wire 186A being coupled to the top guard plate 182 though glide holes 189 urges the top guard plate to glide with respect to the top surface of the motor 40.
- the portion of the top guard plate 182 between the mounting holes 186D may be configured to remain in contact with the motor 40 as the motor 40 moves vertically along an axis 183 with respect to the table top 2.
- top guard plate 182 and the side plates 184 are pivotably connected to the support wall 172 via a pivoting rod (or pin) 188 which extends along the axis 181.
- a pivoting rod (or pin) 188 which extends along the axis 181.
- windows 182A and 182B are provided for ventilation for the motor 40 (see fig. 6 ) and an interface for an additional guard system 230 as will be described in more detail with respect to the guard system embodiments depicted in FIG. 6 .
- FIG. 3 Also depicted in FIG. 3 is part of the height adjustment mechanism 20 including a beveled gear 23, a threaded rod 24 and the threaded member 28.
- the top guard plate 182 and the side plates 184 move about the glide wire 186A along an axis 185. While the motor 40 is depicted in an intermediate position along the axis 183, the reader should appreciate that the top guard plate 182 becomes substantially parallel with the table top 2 (see FIGs. 2 and 4 ) when the motor is at an up position (i.e., when the motor is raised to its highest possible vertical position), and the blade case 260 (see FIGs. 2 and 4 ) is not beveled or tilted with respect to the table top 2.
- the interface between the top guard plate 182 and the glide wire 186A prevents a user from lifting the top guard plate 182 by overcoming the downward forces of gravity of the top guard plate 182 and the side plates 184 and the spring force of the optional torsion spring 186C.
- the clip 186B maintains the base of the U-shaped glide wire 186A near the end of the motor 40, and thereby prevents the base of the glide wire 186A to be raised above the motor 40 even if the user attempts to overcome the aforementioned downward forces. Since the guard plate 182 and the side plates 184 are constrained by the glide wire 186A, these structures limit access to the top portion of the motor 40.

- the top guard plate 192 further interfaces with the rod 198 via hinges (or slots) 197.
- the top guard plate 192 includes windows 192A and 192B.
- the window 192B provides an interface cavity for a guard system 230, further described below (see FIG. 6 ).
- a ventilation window 192C (see FIG. 5A ) is also positioned above the motor 40 to allow a motor fan 42 to ventilate air.
- the top guard plate 192 tilts downward when the motor 40 is lowered along an axis 193 from the up position (depicted in FIG. 4 ) to a down position (i.e., the lowered to the lowest possible position, depicted in FIG. 5A ).
- the top guard plate 192 tilts upward to an orientation that is substantially parallel with the table top 2 (see FIG. 2 ), when the blade case 260 (see FIG. 2 ) is not beveled or tilted with respect to the table top 2.
- the bottom portion of the arcuate end 195 remains in contact with the motor 40 to limit access to the space above the motor 40.
- the guard system 200 and 210A are stationary guard systems that are positioned about the sides of the motor 40. These systems include guard members such as guard plates 202 and 212A and side plates 204 and 214A which are integrally formed with the guard plates 202 and 212.
- the guard plates 202 and 212A terminate at arcuate ends 205 and 215A and are connected to the wall 172 via mounting holes 208 and 218A, respectively.
- the guard systems 200 and 210A are so dimensioned and are thereby configured to limit access to the space around the sides of the motor 40 when the motor 40 is vertically moved from the up position (depicted in FIG. 4 ) to the down position along the axis 193.
- FIG. 5A a plan view of the motor 40 and the guard system 190 is depicted in the down position.

- the guard system 230 is a spring-loaded guard system with guard members that pivot about a pivot axis 191 (see FIG. 4 ). It includes guard members such as a guard plate 232 which spans substantially the width of the blade case 260 (see FIG. 11C ), and optional side plates (not shown) which may be integrally formed with the guard plate 232 forming a unitary U-shaped structure providing added rigidity.
- the guard plate 232 and the side plates (not shown) terminate at an arcuate end or a sliding end 235 which is urged to remain in contact with the bottom side of the table top 2 via a torsion spring 236 (see FIG. 8 ).
- the torsion springs 196 and 236 may be shared between the guard systems 190 and 230.
- a rod (or pin) 238 (see FIG. 8 ) which extends along the axis 191 terminates at the glide rails 26 by terminating fasteners 239.
- the rod 238 also extends through the torsion spring 236.
- the guard plate 232 further interfaces with the rod 238 via hinges or slots (not shown).
- the guard plate 232 tilts with respect to the bottom of the table top 2 when the blade case 260 is beveled so that the saw blade 6 is moved along the arcuate path B-B (see FIG. 1 ) from a square or upright position (i.e., where the blade case 260 is substantially perpendicular to the table top 2 (see FIG. 2 ) to a beveled or tilted position (for example, 45 degrees of bevel, see FIG. 10 ).
- the guard plate 232 tilts leftward (with respect to FIG. 6 , for example) to an orientation that is substantially parallel with the table top 2 (see FIGs. 6 , 7, and 8 ).
- the arcuate end 235 of the guard system 230 fits inside the window 192B of the guard system 190 to prevent interference between these systems as well as to limit access to the internal components.
- the guard plate 232 tilts rightward (with respect to FIG. 6 , for example) to an orientation that is substantially perpendicular to the table top 2.
- the top portion of the arcuate end 235 remains in contact with the bottom side of the table top 2 to limit access to the space defined by the air gap 148 (see FIG. 2 ).
- the guard system 240 is also a spring-loaded guard system with guard members that pivot about a pivot axis 241 (the pivot axis 241 comes in and out of the page, see FIG. 9 ). It includes guard members such as a guard plate 242 which spans the width of the blade case 260, and side plates 244 which are integrally formed with the guard plate 242. The guard plate 242 and the side plates 244 terminate at an arcuate end 245 which is urged to remain in contact with the blade case 260 via a torsion spring 246 (see FIGs. 6 and 9 ).

- the guard plate 242 tilts with respect to the blade case 260 when the blade case 260 is beveled from the square position to the substantial beveled position (see FIG. 10 ).
- the guard plate 232 tilts leftward (with respect to FIG. 6 , for example) to an orientation that is substantially perpendicular with the table top 2 (see FIGs. 6 , 7, and 9 ) and only the left side of the arcuate end 245 is in contact with the blade case 260.
- the guard plate 232 tilts rightward (with respect to FIG. 6 , for example) to an orientation where substantially all of the guard plate 242 contacts the blade case 260. Since during the entire beveling movement of the blade case 260, the left portion of the arcuate end 245 remains in contact with the blade case 260, access is limited to the space by the air gap 148 (see FIG. 2 ).
- FIG. 11A, 11B, and 11C devices are depicted for limiting movement of the guard systems 230 and 240.
- These guard plates 232 and 242 of these systems are urged to make contact with the bottom side of the table top 2 and the blade case 260 by the urging of the associated torsion springs (236 and 246).

It is understood that no limitation to the scope of the invention is thereby intended. It is further understood that the present invention includes any alterations and modifications to the illustrated embodiments and includes further applications of the principles of the invention as would normally occur to one of ordinary skill in the art to which this invention pertains.
- The embodiments described in the present disclosure provide structures that limit access of a user to internal components of a table saw assembly when a motor of the table saw assembly is in different position.
- Referring to
FIG. 1 , atable saw assembly 1 is depicted. Thetable saw assembly 1 includes atable top 2 which includes asaw blade opening 4. Asaw blade 6 extends through thesaw blade opening 4 and is configured to rotate about an axis passing through acoupling 8. A window is provided about the saw blade opening 4 to partially depict thesaw blade 6 and thecoupling 8, below the surface of thetable top 2. - The
table saw assembly 1 also includes atable extension 5 and arip fence 10. Thetable extension 5 is coupled to thetable top 2 via rails 11 and thelever lock 12. Therip fence 10 is coupled to thetable top 2 or thetable extension 5 via rails 11 and alock 9. Thelock 9 enables a user to lock therip fence 10 in a stationary position with respect to thetable top 2 and the rails 11. - The
table saw assembly 1 further includes ahousing 13 coupled to abase portion 14 and which includes anarcuate opening 15. Thearcuate opening 15 receives a blade position adjustment mechanism which includes awheel 16 for adjusting the height of thesaw blade 6 about thetable top 2 and abevel adjustment lever 17 which controls the tilt or bevel angle of thesaw blade 6 along an arcuate path B-B. There is also an on/offswitch 18 depicted inFIG. 1 which provides power to the table sawassembly 1. Also, through thearcuate opening 15, asupport arrangement 150 is depicted, which is further described below with reference toFIG. 2 . - The table saw
assembly 1 may be of a push-pull type where a workpiece to be shaped is placed on thetable top 2 and remains stationary while theblade 6 is moved along an axis defined by arrows V-V. Alternatively, the table sawassembly 1 may of the type where thesaw blade 6 remains stationary with respect to the axis defined by the arrows V-V, and the workpiece is moved toward thesaw blade 6. - Referring to
FIG. 2 , a saw bladeheight adjustment mechanism 20 is depicted. The saw bladeheight adjustment mechanism 20 is known to a person of ordinary skill in the art and is therefore described herein, briefly. The saw bladeheight adjustment mechanism 20 includes ashaft 21 which is coupled to abeveled gear 22 which is coupled to anotherbeveled gear 23. Thebeyeled gear 23 is coupled to arod 24 with a threaded portion 29 (seeFIG. 5A ) which interfaces with a threaded member 28 (shown inFIG. 3 ) which is fixedly coupled to amotor 40. Themotor 40 glides on theglide rods 26. Accordingly, by turning theshaft 21, the threadedportion 29 of therod 24 turns within the threadedmember 28 which causes themotor 40, and thesaw blade 6 attached thereto, to raise and lower with respect to thetable top 2. - Also depicted in
FIG. 2 , is a perspective view of thesupport arrangement 150 coupled to acover assembly 250. Thecover assembly 250 couples to asupport wall 172 of thesupport arrangement 150 withfastener assemblies 52. At one periphery of thesupport wall 172 is aside wall 173 and at another periphery is anotherside wall 174. Thecover assembly 250 includes aside wall 273 which is positioned adjacent theside wall 173, another side wall (not shown) positioned opposite theside wall 273 and which is positioned adjacent theside wall 174, and a cover wall (not shown) which is positioned between theside walls 273 and 274. Theside walls support wall 172. Similarly, the side walls of thecover assembly 250 are in the form of a flange that are integrally formed with and are substantially perpendicular to the cover wall (not shown). Theside wall 174, the periphery of thesupport wall 172 which joins theside wall 174, the side wall (not shown) of the cover assembly opposite to theside wall 273 and a periphery of the cover wall (not shown) are all arcuate in shape. - A combination of the
support arrangement 150 and thecover assembly 250 form ablade case 260. Theblade case 260 includes ablade chamber 262 which is defined by thesupport wall 172 on one side of thesaw blade 6, the cover wall (not shown) on an opposite side of thesaw blade 6, and the side walls of thesupport arrangement 150 and thecover assembly 250 which are along outer perimeters of theblade chamber 262. As themotor 40 is coupled to theglide rods 26 which are connected to the support wall 172 (i.e., part of the blade case 260), the motor is also coupled to theblade case 260. Accordingly, thesaw blade 6 is partially positioned within theblade case 260 and within theblade chamber 262 and is configured to move vertically within theblade chamber 262. Thesupport wall 172 and the cover wall 274 are separated by a space defined by the width of the side walls of thesupport arrangement 150 and thecover assembly 250, in which theblade chamber 262 is positioned. - Also depicted in
FIG. 2 is a rivingknife 7 which is positioned adjacent to thesaw blade 6. Configuration and function of the rivingknife 7 is known to a person of ordinary skill in the art. - The top edge of the
wall 172 is separated by anair gap 148 from the bottom side of thetable top 2. While some of the structures described in the present disclosure are directed to limiting access of a user to internal compartments of the table saw defined by the space defined by theair gap 148, some of the other structures are directed to limiting access of the user to the space adjacent themotor 40. - Referring to
FIG. 3 , an embodiment of aguard system 180 is depicted. Theguard system 180 is optionally a spring-loaded guard system with guard members that pivot about apivot axis 181. Theguard system 180 includes guard members such as atop guard plate 182 andside plates 184 shaped in the form of triangles which are integrally formed on opposite sides of thetop guard plate 182 forming a unitary U-shaped structure providing added rigidity. - The
guard system 180 also includes a glide wire (or a rail member) 186A, aclip 186B, and anoptional torsion spring 186C. Theglide wire 186A is a U-shaped structure and directs thetop guard plate 182 and theside plates 184 to slide according to the predefined path of theglide wire 186A. Theglide wire 186A is connected to themotor 40 by a three-point connection arrangement. Theclip 186B connects the base of theU-shaped glide wire 186A to themotor 40, while the ends of the U-Shaped glide-wire 186A are connected to themotor 40 at mountingholes 186D positioned on opposite sides of the motor 40 (only one mountinghole 186D is depicted inFIG. 3 ). Theoptional torsion spring 186C urges thetop guard plate 182 andside plates 184 downward toward themotor 40, while theglide wire 186A being coupled to thetop guard plate 182 though glide holes 189 urges the top guard plate to glide with respect to the top surface of themotor 40. The portion of thetop guard plate 182 between the mountingholes 186D may be configured to remain in contact with themotor 40 as themotor 40 moves vertically along anaxis 183 with respect to thetable top 2. - The
top guard plate 182 and theside plates 184 are pivotably connected to thesupport wall 172 via a pivoting rod (or pin) 188 which extends along theaxis 181. On thetop guard plate 182windows fig. 6 ) and an interface for anadditional guard system 230 as will be described in more detail with respect to the guard system embodiments depicted inFIG. 6 . - Also depicted in
FIG. 3 is part of theheight adjustment mechanism 20 including abeveled gear 23, a threadedrod 24 and the threadedmember 28. - In operation when the
beveled gear 23 is turned to raise and lower themotor 40 along theaxis 183, thetop guard plate 182 and theside plates 184 move about theglide wire 186A along anaxis 185. While themotor 40 is depicted in an intermediate position along theaxis 183, the reader should appreciate that thetop guard plate 182 becomes substantially parallel with the table top 2 (seeFIGs. 2 and4 ) when the motor is at an up position (i.e., when the motor is raised to its highest possible vertical position), and the blade case 260 (seeFIGs. 2 and4 ) is not beveled or tilted with respect to thetable top 2. - The interface between the
top guard plate 182 and theglide wire 186A prevents a user from lifting thetop guard plate 182 by overcoming the downward forces of gravity of thetop guard plate 182 and theside plates 184 and the spring force of theoptional torsion spring 186C. Theclip 186B maintains the base of theU-shaped glide wire 186A near the end of themotor 40, and thereby prevents the base of theglide wire 186A to be raised above themotor 40 even if the user attempts to overcome the aforementioned downward forces. Since theguard plate 182 and theside plates 184 are constrained by theglide wire 186A, these structures limit access to the top portion of themotor 40. - Referring to
FIG. 4 , threeguard systems motor 40 and limit a user's access to the area around themotor 40. Theguard system 190 is a spring-loaded guard system with guard members that pivot about apivot axis 191. It includes guard member such as atop guard plate 192, andside plates 194 shaped in the form of triangles which are integrally formed with thetop guard plate 192 forming a unitary U-shaped structure providing added rigidity. Thetop guard plate 192 and theside plates 194 terminate at anarcuate end 195 which is urged to remain in contact with the motor via atorsion spring 196. A rod (or pin) 198 which extends along theaxis 191 terminates at the glide rails 26 by hooks orfasteners 199. Therod 198 also extends through thetorsion spring 196. Thetop guard plate 192 further interfaces with therod 198 via hinges (or slots) 197. - The
top guard plate 192 includeswindows window 192B provides an interface cavity for aguard system 230, further described below (seeFIG. 6 ). Aventilation window 192C (seeFIG. 5A ) is also positioned above themotor 40 to allow amotor fan 42 to ventilate air. - In operation, the
top guard plate 192 tilts downward when themotor 40 is lowered along anaxis 193 from the up position (depicted inFIG. 4 ) to a down position (i.e., the lowered to the lowest possible position, depicted inFIG. 5A ). In the up position, thetop guard plate 192 tilts upward to an orientation that is substantially parallel with the table top 2 (seeFIG. 2 ), when the blade case 260 (seeFIG. 2 ) is not beveled or tilted with respect to thetable top 2. During the vertical movement of themotor 40 along theaxis 193, the bottom portion of thearcuate end 195 remains in contact with themotor 40 to limit access to the space above themotor 40. - The
guard system motor 40. These systems include guard members such asguard plates side plates guard plates 202 and 212. Theguard plates wall 172 via mountingholes guard systems motor 40 when themotor 40 is vertically moved from the up position (depicted inFIG. 4 ) to the down position along theaxis 193. - Referring to
FIG. 5A a plan view of themotor 40 and theguard system 190 is depicted in the down position. As described above, thewindow 192C provides ventilation for themotor 40. Thewindow 192C as well aswindows 192A (depicted inFIG. 5A ) and 192B are sufficiently small to limit access to the space above the motor through the windows. However, these windows are sufficiently large to allow ventilation and interface by another guard system, further described below. - Also depicted in
FIG. 5A is a motorlower guard 220 connected to themotor 40 for limiting access to the bottom side of the motor. The motorlower guard 220 also limits dust and debris generated during cutting operations from entering into themotor 40, as described in aU.S. Pat. App. S/ N 12/856,568 - Further depicted in
FIG. 5A , and more clearly shown inFIG. 5B , is analternative embodiment 210B of thestationary guard system 210A depicted inFIG. 4 . Thestationary guard system 210B includes guard members such as aguard plate 212B and aside plate 214B which is integrally formed with theguard plate 212A. Theguard plate 212B terminates at an arcuate end 215B and is connected to thewall 172 via mountingholes 218A. Theguard systems 210B is so dimensioned and is thereby configured to limit access to the space around the sides of themotor 40 when themotor 40 is vertically moved from the up position (depicted inFIG. 4 ) to the down position (depicted inFIG. 5A ) along the axis 193 (seeFIG. 4 ). - Referring to
FIGs. 6 ,7, 8, and 9 , side views of parts of the table sawassembly 1 are depicted. InFIG. 6 , themotor 40 is depicted in the up position, such that theblade 6 is extended above thetable top 2 through thesaw blade opening 4. InFIG. 7 , themotor 40 is depicted in the down position such that thesaw blade 6 is completely below thetable top 2. - While the
guard systems motor 40, respectively, a guard system 230 (depicted inFIGs. 6 ,7, and 8 ) and a guard system 240 (depicted inFIGs. 6 ,7, and 9 ), limit access between theblade case 260 and the bottom of the table top 2 (i.e., the space defined by the air gap 148). - The
guard system 230 is a spring-loaded guard system with guard members that pivot about a pivot axis 191 (seeFIG. 4 ). It includes guard members such as aguard plate 232 which spans substantially the width of the blade case 260 (seeFIG. 11C ), and optional side plates (not shown) which may be integrally formed with theguard plate 232 forming a unitary U-shaped structure providing added rigidity. Theguard plate 232 and the side plates (not shown) terminate at an arcuate end or a slidingend 235 which is urged to remain in contact with the bottom side of thetable top 2 via a torsion spring 236 (seeFIG. 8 ). The torsion springs 196 and 236 may be shared between theguard systems FIG. 8 ) which extends along theaxis 191 terminates at the glide rails 26 by terminating fasteners 239. The rod 238 also extends through the torsion spring 236. Theguard plate 232 further interfaces with the rod 238 via hinges or slots (not shown). - In operation, the
guard plate 232 tilts with respect to the bottom of thetable top 2 when theblade case 260 is beveled so that thesaw blade 6 is moved along the arcuate path B-B (seeFIG. 1 ) from a square or upright position (i.e., where theblade case 260 is substantially perpendicular to the table top 2 (seeFIG. 2 ) to a beveled or tilted position (for example, 45 degrees of bevel, seeFIG. 10 ). In the square position, theguard plate 232 tilts leftward (with respect toFIG. 6 , for example) to an orientation that is substantially parallel with the table top 2 (seeFIGs. 6 ,7, and 8 ). In this position, thearcuate end 235 of theguard system 230 fits inside thewindow 192B of theguard system 190 to prevent interference between these systems as well as to limit access to the internal components. In the beveled position (seeFIG. 10 ), theguard plate 232 tilts rightward (with respect toFIG. 6 , for example) to an orientation that is substantially perpendicular to thetable top 2. During the beveling movement of theblade case 260, the top portion of thearcuate end 235 remains in contact with the bottom side of thetable top 2 to limit access to the space defined by the air gap 148 (seeFIG. 2 ). - The
guard system 240 is also a spring-loaded guard system with guard members that pivot about a pivot axis 241 (thepivot axis 241 comes in and out of the page, seeFIG. 9 ). It includes guard members such as aguard plate 242 which spans the width of theblade case 260, andside plates 244 which are integrally formed with theguard plate 242. Theguard plate 242 and theside plates 244 terminate at anarcuate end 245 which is urged to remain in contact with theblade case 260 via a torsion spring 246 (seeFIGs. 6 and9 ). A rod (or pin) 248 (seeFIG. 8 ) which extends along theaxis 241 terminates at the bottom side of thetable top 2 by terminatingfasteners 249. Therod 248 also extends through thetorsion spring 246. Theguard plate 242 further interfaces with therod 248 via hinges or slots (not shown). - In operation, the
guard plate 242 tilts with respect to theblade case 260 when theblade case 260 is beveled from the square position to the substantial beveled position (seeFIG. 10 ). In the square position, theguard plate 232 tilts leftward (with respect toFIG. 6 , for example) to an orientation that is substantially perpendicular with the table top 2 (seeFIGs. 6 ,7, and 9 ) and only the left side of thearcuate end 245 is in contact with theblade case 260. In the beveled position (seeFIG. 10 ), theguard plate 232 tilts rightward (with respect toFIG. 6 , for example) to an orientation where substantially all of theguard plate 242 contacts theblade case 260. Since during the entire beveling movement of theblade case 260, the left portion of thearcuate end 245 remains in contact with theblade case 260, access is limited to the space by the air gap 148 (seeFIG. 2 ). - Referring to
FIG 11A, 11B, and 11C , devices are depicted for limiting movement of theguard systems guard plates table top 2 and theblade case 260 by the urging of the associated torsion springs (236 and 246). Travel limiting member are provided to avoid a situation where a user can overcome the force of these springs and thereby reach inside the internal compartments of thesaw assembly 1. InFIG. 11A , ashoulder screw 232A is depicted which extends through theguard plate 232. Theshoulder screw 232A limits downward movement of theguard plate 232. Similarly, as depicted inFIG. 11B , ashoulder screw 242A is depicted which extends through theguard plate 242. Theshoulder screw 242A limits leftward movement of theguard plate 242 with respect toFIG. 11B . InFIG. 11C , an alternative embodiment to theshoulder screw 232A is depicted.Fasteners 232B are positioned at opposite ends of theguard plate 232 and acable 232C is fastened between them. Thecable 232C limits how much theguard plate 232 may be pulled away from the bottom side of thetable top 2. As an alternative embodiment to theshoulder screw 242A, a cable assembly (not shown) similar to thefasteners 232B and thecable 232C can be configured to also limit how far theguard plate 242 can pivot away from theblade case 260. The shoulder screws 232A and 242A, as well as thefasteners 232B may require a specialty tool to prevent unauthorized removal of these limiting devices. - Referring to
FIG. 12 an alternative embodiment of atable saw assembly 301 is depicted. The table sawassembly 301 is described in aU.S. Pat. App. S/ N 12/834,795assembly 301 includes afront leg unit 320 and a rear leg unit (not shown, opposite the front leg unit 320). Thefront leg unit 320 includes downwardly extendingleg portions leg portions - Between the downwardly extending
legs guard system 310 is depicted. The guard system is of the stationary type and includes aguard plate 312 andside plates 314 integrally formed with theguard plate 312 forming a U-shaped structure for added rigidity. Theside plates 314 include mounting holes for mounting theguard system 310 to the downwardly extendinglegs fasteners 314. Theguard plate 312 is configured to limit access to the compartments of the table sawassembly 301. - The guard plates of the spring-loaded pivoting type of the internal guard systems described above (for example, the
guard plate 242 of the internal guard assembly 240), may be further configured to pivot away from respective mating surfaces (for example, the blade case 260) to allow limited access for the user. The user may be able to use this limited access as a handle to lift thesaw assembly 1/301. - While the invention has been illustrated and described in detail in the drawings and foregoing description, the same should be considered as illustrative and not restrictive in character.
